home.c, dda.c: consider endstops on both axis ends when homing. 

Previously, when backing off of X_MIN, X_MAX was also checked,
which of course was already open, so it signals endstop release
even while X_MIN is still closed. The issue exposed only when
endstops on both ends of an axis were defined, a more rare situation.

Essentially the fix simply makes a distinct endstop check case
for each side of each axis.

This even makes binary size 40 bytes smaller for the standard case.
